Taxonomy
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Hymenoptera
- Family: Tenthredinidae (common sawflies)
- Genus: Aglaostigma
- Species: Aglaostigma fulvipes (Klug, 1816)
Etymology
The specific epithet fulvipes derives from Latin fulvus (“tawny, yellow‑brown”) and pes (“foot”), likely referring to the coloration of the legs.
Description
Aglaostigma fulvipes is a small sawfly, typically ranging from 6 to 9 mm in length. Adults possess the typical sawfly morphology: a broad waist (absence of a constricted “wasp waist”), membranous wings with visible venation, and chewing mouthparts. The body is generally dark (black to dark brown), while the legs are described in some sources as having a yellowish to fulvous tint, consistent with the species name. Detailed morphological characters used for identification (e.g., antennal segment counts, wing‑cell patterns) are documented in specialist taxonomic keys for European Tenthredinidae.
Distribution and Habitat
- Geographic range: Recorded throughout much of Europe, including the United Kingdom, France, Germany, the Netherlands, Scandinavia, and the Baltic states.
- Habitat: Primarily associated with habitats where host plants occur, such as riparian zones, wetlands, and mixed deciduous woodlands.
Biology and Ecology
- Host plants: Larvae have been reported to feed on the foliage of willows (Salix spp.). Some records also suggest possible feeding on other Salicaceae, but definitive host‑plant associations are limited to Salix.
- Life cycle: Like other sawflies, A. fulvipes undergoes complete metamorphosis with egg, larval, pupal, and adult stages. Adults are typically active in late spring to early summer, coinciding with the emergence of fresh willow leaves.
- Behavior: Adults are diurnal and are often observed perched on foliage or low vegetation. Larvae are leaf‑feeding and can be gregarious in early instars.
Conservation Status
There is no specific conservation assessment for Aglaostigma fulvipes on the IUCN Red List. The species is generally considered locally common within suitable habitats and does not appear to be under significant threat.
